Description

Technical Field

[0001] This application relates to the field of elliptical machine technology, and in particular to an elliptical machine with a pull-out storage design. Background Technology

[0002] In recent years, with increasing attention to healthy lifestyles, the home and commercial fitness equipment market has experienced rapid growth. Among them, the elliptical trainer, as a low-impact, full-body aerobic exercise device, is gaining popularity due to its low joint stress and significant exercise effects.

[0003] For some home treadmills, their large size makes storage difficult. Although there are foldable treadmills on the market, the folding method of the base frame and the fixing structure after folding are quite complicated. Therefore, there is a need for an elliptical machine on the market that can easily fold and fix the base frame.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a pull-out elliptical machine to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a pull-out elliptical machine, comprising: a base frame including a first tube, a second tube, and a third tube, wherein the first tube and the second tube are hinged to each other, the third tube is slidably disposed with respect to the second tube, and a limiting post is provided at one end of the third tube connected to the second tube; a locking hole is provided at the top of the first tube to cooperate with the limiting post; a main frame disposed at the top of the first tube; and a pedal linkage structure disposed at both ends of the main frame for simulating walking, running, or climbing stairs. The end of the pedal linkage structure connected to the main frame is detachable. By rotating the second tube and the third tube, the second tube is made to form a certain angle with the first tube. By pushing the third tube, the limiting post cooperates with the locking hole, and the base tube enters a folded state.

[0007] In some embodiments, a rotating pin is fixedly provided on the first tube, and a rotating connecting part is installed at the end of the second tube that is connected to the first tube.

[0008] In some embodiments, a first step is formed at one end of the second tube, and a second step is formed between the second tube and the rotatable connection portion. In the folded state, the contours of the first step and the second step match.

[0009] In some embodiments, the base frame has foot tubes perpendicular to it at both ends, and the pedal linkage structure abuts against the foot tubes in the folded state.

[0010] In some embodiments, a handle is provided on one side of the foot tube connected to the third tube.

[0011] In some embodiments, a limiting block is provided at the bottom of the second tube, the limiting block including a limiting part and a sliding part, and a sliding groove is provided at the bottom of the third tube to cooperate with the sliding part, and a limiting groove is provided at one end of the sliding groove to cooperate with the limiting part.

[0012] The beneficial effects of this application are as follows: when the base frame needs to be folded, the pedal linkage structure can be folded and stored first, and then the second and third tubes can be rotated directly so that only the first tube of the elliptical machine is placed on the ground, reducing space occupation. Then the third tube is pushed into the second tube, and the angle of the second tube is fixed by the limiting post and the locking hole. The entire operation space is small. At the same time, in order to prevent the third tube from coming out, the limiting block can limit the movement distance of the third tube, ensuring the safe use of the elliptical machine.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0021] In the embodiments of this application, please refer to Figure 1-5 As shown, this application provides a pull-out elliptical trainer, mainly comprising: a base frame 1, including a first tube 11, a second tube 12, and a third tube 13, wherein the first tube 11 and the second tube 12 are hinged to each other, and the third tube 13 is slidably disposed with respect to the second tube 12, and a limiting post 131 is provided at one end of the third tube 13 connected to the second tube 12, and a locking hole 111 is provided at the top of the first tube 11 to cooperate with the limiting post 131; a main frame 2, disposed at the top of the first tube 11; and a pedal linkage structure 3, disposed at both ends of the main frame 2, used to simulate walking, running, or climbing stairs; the end of the pedal linkage structure 3 connected to the main frame 2 is detachable.

[0022] Specifically, when the base frame 1 needs to be folded, the pedal linkage structure 3 is first disassembled or folded so that it does not obstruct the rotation path of the base frame 1. By rotating the second tube 12 and the third tube 13, a certain angle is formed between the second tube 12 and the first tube 11 until the limiting post 131 and the lock hole 111 are on the same plane. The third tube 13 is pushed in so that the limiting post 131 enters the lock hole 111. At this time, the second tube 12 cannot rotate. When unlocking is required, the third tube 13 is simply pulled out so that the limiting post 131 is disengaged from the lock hole 111, and the second tube 12 can regain its rotation ability.

[0023] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0024] Preferably, a rotating pin 112 is fixedly provided on the first tube 11, and a rotating connecting part 121 is installed at the end of the second tube 12 that connects to the first tube 11. (Refer to...) Figure 3-4As shown, in order to prevent the rotation between the first tube 11 and the second tube 12 within a certain angle from interfering with each other, a first step 113 is formed at one end of the first tube 11, and a second step 1211 is formed between the second tube 12 and the rotating connection part 121. In the folded state, the outlines of the first step 113 and the second step 1211 match.

[0025] Reference Figure 2 As shown, the base frame 1 has foot tubes 14 perpendicular to it at both ends. In the folded state, the pedal linkage structure 3 abuts against the foot tubes 14. With this configuration, the pedal linkage structure 3 does not require an additional locking mechanism in the folded state, reducing the structural complexity.

[0026] Preferably, in order to facilitate the user to pull out the third tube 13, a handle 141 is provided on one side of the foot tube 14 connected to the third tube 13.

[0027] Specifically, refer to Figure 4-5 As shown, a limiting block 122 is provided at the bottom of the second tube 12. The limiting block 122 includes a limiting part 1221 and a sliding part 1222. A sliding groove 132 is provided at the bottom of the third tube 13 to cooperate with the sliding part 1222. One end of the sliding groove 132 is provided with a limiting groove 133 that cooperates with the limiting part 1221. The cooperation process between the limiting block 122 and the third tube 13 is as follows:

[0028] When the bottom tube is in the unfolded state, one end of the limiting block 122 will abut against the ground, and at this time, the limiting part 1221 and the limiting groove 133 cooperate to prevent it from moving radially until the first tube 11 and the second tube 12 are rotated and lifted. During the lifting process, the limiting block 122 will naturally come out under the action of gravity or be pulled out manually. During this process, the sliding part 1222 enters the limiting groove 133 and can enter the sliding groove 132. The limiting block 122 loses its limiting function. At this time, the second tube 12 can slide in the third tube 13 to make the bottom tube enter the folded state. When it is necessary to disengage from the folded state, pull out the third tube 13 so that the sliding part 1222 enters the limiting groove 133. Then rotate the second tube 12 to lay it flat on the ground. One end of the limiting block 122 will be abutted by the ground, so that the limiting part 1221 will enter the limiting groove 133 again, completing the locking of the unfolded state.

[0029] The various embodiments of this application have been described in detail above. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description. Finally, it should be noted that the above descriptions are merely preferred embodiments of this application, and the foregoing embodiments are only used to illustrate the technical solutions of this application, not to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
